Eight vertically oriented interface module slots support the installation of up to eight 9920-16C interface modules. Each interface module supports up to sixteen 100 Gb ports, for a total of 128 100Gb ports. There is also one feature slot that is reserved for future use. The 9920-16C interface module is hot-swappable.
The front panel of the 9920-16C modules contains four LEDs located between the upper and lower ports. The two LEDs on the left are both green and indicate the channel within the port, which is indicated by the remaining two LEDs. The font panel also contains a Channel Selector button, which cycles through the four selectable channels.
Note
Electrostatic discharge (ESD) can damage electronic circuits. Do not touch electronic hardware unless you wear a grounding wrist strap or other static-dissipating device.
Note
Keep the metal cover plate in place over empty module slots. An empty module slot allows air into the chassis, which reduces the negative pressure in the chassis. This reduces airflow to the installed modules.
The following table provides a description of the ports and LED indicators for all IOC models, as shown in the preceding figure:
|
1 = 16 port 40Gb/100 Gbps QSFP ports, even ports (2, 4, 6, 8, 10, 12, and 14) can be patitioned to 4 x 25Gbps or 4 x 10Gbps |
4 = Interface module ejector lever |
|
2 = Channel select button |
5 = LED status indicators: Left two LEDs indicate channel. Right two LEDs indicate port speed and link status. LEDs are for every port pair. |
|
3 = Interface module handle release |
